Cell-free Fetal DNA Is Increased in Plasma of Women with Hyperemesis Gravidarum

Abstract
Nausea and vomiting of moderate intensity are especially common complaints in early gestation. Hyperemesis gravidarum (HG), which is the most severe form of this disorder, occurs in 0.5–2% of pregnancies and is associated with weight loss, ketonemia, ketonuria, electrolyte imbalance, dehydration, and possible hepatic and renal damage.
